Former Division 1 athletes helping women feel stronger through realistic, effective workouts.

We built the workout app we always wanted

As athletes, fitness has always been part of our lives. But once careers, travel, and busy schedules entered the picture, we realized most fitness programs simply weren’t realistic.

So we created SISSFiT — an app designed to deliver challenging, motivating workouts that fit into everyday life.
